Hallo liebe Java User Group Mitglieder! Diesmal haben wir Peter Kranz mit seinem interaktiven Talk zu den unterschiedlichen Java-Versionen zu Gast. Wir freuen uns euch zu sehen (virtuell oder vor Ort). * 18:00 Uhr: Einlass * 18:30 Uhr: Talk * ab 19:30: Ausklang des Abends Dank an [adesso](https://www.adesso.de/de/unternehmen/standorte/nuernberg.jsp) für Location, Bier und Pizza! \-\-\- Java entwickelt sich seit Version 9 im Halbjahresrhythmus weiter – mit Records, Pattern Matching, Virtual Threads und vielen weiteren Features. Doch wer hat schon die Zeit, 17 Releases im Detail zu verfolgen? Die Fülle an Neuerungen ist enorm, und je nach Projekt und Interesse sind ganz unterschiedliche Features relevant. Ein klassischer Vortrag kann hier nur einen starren Pfad durch die Feature-Landschaft bieten. Dieser Talk geht einen anderen Weg: als interaktiver Dungeon Crawler. Das Publikum entscheidet gemeinsam, welchen Themenkomplex es als Nächstes erkunden will – Moderne Sprach-Features, Concurrency, APIs, JVM-Tooling oder experimentelle Preview-Features. Jede Entscheidung führt tiefer in den Dungeon und schaltet neue Level frei. So entsteht bei jedem Vortrag ein einzigartiger Pfad durch die Java-Versionen 9 bis 26. Wie in einem echten Dungeon Crawler sammelt das Publikum dabei XP und wird am Ende einer Klasse zugeordnet – vom Warrior mit Fokus auf Performance bis zum Wizard der Sprach-Features. Ob Einsteiger:in oder erfahrene:r Entwickler:in: Jede Session liefert praxisnahe Einblicke in genau die Java-Features, die das Publikum am meisten interessieren. Kein Vortrag gleicht dem anderen – und der einzige Weg, alles zu sehen, ist wiederzukommen. \-\-\- Dein Vortrag bei der Java Usergroup Nürnberg! Hast du dich in letzter Zeit in deinem Projekt oder privat mit einem interessanten Thema beschäftigt? Vermutlich ist das nicht nur für dich selbst interessant! Hast du Lust, selber einmal einen Vortrag bei der Java-Usergroup Nürnberg zu halten? Wir sind nicht nur auf Java-Themen fokussiert, sondern beschäftigen uns gern mit und um alles über Software Entwicklung und IT. Wir wollen bei der JUG nicht nur bekannten Speaker\*innen eine Plattform geben und die neuesten State-of-the-Art Technologien vorstellen. Wir freuen uns auch besonders, wenn wir Themen aus unserem technologischen (Arbeits-)alltag Raum geben zu können. Melde dich gerne bei uns, wenn du dazu Lust hast, wir geben wenn gewünscht gerne auch Hilfestellung bei der Vorbereitung!

When judging morality, should we prioritize **intentions/duty** or **outcomes/results**? It introduces two influential philosophers as representatives of these approaches. * **Immanuel Kant (deontology):** An action is moral when it is done from **duty** and follows rational, universal principles (the **categorical imperative**). Certain acts—like lying—are wrong regardless of the consequences; you can’t do a wrong thing for a right reason. * **John Stuart Mill (utilitarian consequentialism):** The morality of an action is determined by its **effects**, specifically how much **happiness/well-being** it produces. Mill argues that some pleasures are “higher” than others, and that good intentions don’t redeem harmful outcomes. ## Discussion Questions 1. **The lying dilemma:** A murderer comes to your door and asks if your friend is hiding inside. Kant would say you must not lie. 2. **Can good intentions rescue a bad outcome?** 3. **The organ harvest problem:** A surgeon has five patients dying of organ failure and one healthy patient in for a checkup. Killing the one to harvest organs would save five lives, and the math works out for the utilitarian. Why does this feel so deeply wrong? Is that feeling a point in Kant's favor, or just a bias we should overcome? 4. **Do rules need exceptions?** Kant insists moral rules must be universal, with no exceptions. But most of us can imagine extreme scenarios where any rule seems like it should bend. Does the need for exceptions fatally undermine deontology, or is the strength of the system precisely that it refuses to bend? 5. **Who gets to calculate the consequences?** Utilitarianism asks us to maximize good outcomes, but we're notoriously bad at predicting consequences. If we can't reliably know the results of our actions, is it practical to base our entire moral system on outcomes? Does this uncertainty push us back toward rules and principles? 6. **Everyday morality:** Think about a real moral decision you've made recently, even a small one. Did you reason more like a Kantian (what's the right thing to do in principle?) or more like a utilitarian (what will produce the best result?)? Do most people naturally lean one way? 7. **Justice vs. the greater good:** A town can prevent a deadly plague by sacrificing one innocent person. The greater good is clearly served. But is it just? Can an action be morally right and deeply unjust at the same time? 8. **The big synthesis question:** Are these two systems actually opposed, or do they often arrive at the same answers by different paths? Is it possible that we need both: rules to guide us in the moment and consequences to evaluate systems and policies over time?
